Pressure regulation method The potentiometer faces the chest and counterclockwise to boost!     Some customers have reported that the module output voltage cannot be adjusted and is always equal to the input voltage. When you encounter this problem, please turn the potentiometer counterclockwise for more than 10 turns, then use the module to adjust the voltage normally. 1. Module characteristics (boost module): 1) Output current: 2A 2) Input voltage: 2 v ~ 24 v 3) Output voltage: > 5V-28 v 4). Efficiency: > 93% 2. Mechanical properties: 1). Product size: 36mm * 17mm * 14mm 3. How to use After the module, + and - 2 ~ 24 v, the adjustment potentiometer can adjust the output voltage, the output voltage is higher than the input voltage 4. Notes 1). Input voltage should not exceed input voltage 2). Peak current output current does not exceed 2A
